Hollywood's Top Colorist Dishes

What's the secret to Hollywood's best hair color? Perhaps the question is really who. Meet Rita Hazan, a New York-based colorist responsible for tons of celebrity strands. For our March issue, Hazan dished on her top clients:

1. Jennifer Lopez's sunny highlights: "When I started working with Jennifer in the '90s, I thought it would be fun to experiment with honey highlights. I had no idea it would become such a big part of her look," the colorist says. Now Lopez gets "inside highlights" that show when she flips her hair.

3. Jessica Simpson's buttery blond: "The first time Jessica came to see me [at age 18] was to fix a bleached-out platinum dye-job," says Hazan. Now Simpson receives a base of golden blond with paler blond highlights.
